My question on using a single panel, was simply so I wouldn't have to have 2 panels. I figured your answer was the proper one (safe one!) and will just put in 2 panels. Down the road if i can afford one really nice TSW big boy, then I can do something else with the 2nd panel.

I am going to run the "K.I.S.S." flag up the poll and lets see how this works.
We are talking about inverter(s) less than 600 watts, so do we really need a AC distribution center?? I can not see why, we need just one fuse/breaker for each inverter. If you use 14-2 wire or bigger, you really do not need either, why, the inverter can't supply current to damage the wire.
Now, lets look at this item:http://www.amazon.com/Cooper-Bussmann-BP-SSU-Switch-Holder/dp/B001AQ2B96
It is a fuse holder and switch in-one for a 2X4 box. Use one for each inverter. Now you have separate lines with a switch and fuse. For each box, Run a cord with male plug to one inverter and run the 14-2 romex for the cabin circuit(s).

Not knowing any better though, does anyone know if I can run the MS 300watt SureSine inverter with a 'real' neutral, or am I still in that '2-hot sides' mode?

I am sorry to piggy back this thread, I was reading it and it somewhat pertains to what I am doing. The specifications of the inverter I am trying to connect is a 240vac inverter 7kw it has 3 terminal posts positive, negative, and earth ground. When i test the output of the inverter I get 240 across the positive and negative legs. When I test either leg to earth ground I get nothing.
This tells me the inverter produces single phase 240vac not the two phase 120vac on each leg like I thought it did. I want to make sure before I transfer my house circuits over to the new breaker box that I have it connected right.
On one main lug I connected the positive cable from inverter, on the other main lug I connected the negative. I connected the Earth Ground to the ground bar of new breaker box and connected that to the house grounding rod. Okay, I know the electric company sends two single phase 120vac legs to my house breaker box 180 degrees out of phase of each other.
The inverter that I have doesn't have two phase capabilities; so what I did was connect one 15 amp circuit off each main lug and connected both common wires to ground making both circuits become series; but I tested this and burned out one of my test loads; one load got more voltage than the other which was rated at 115 volts and the other was rated at 117volts. The one rated at 115 burned out. What did I do wrong?
I have a step down transformer 480/240 to 240/120; I tried to connect the 240 from the inverter to the primary but the it goes into protect mode with no power output. I have to connect 240 on one half of the transformer's primary to get it to produce 120 on the secondary. Is there somthing I am missing. The primary has a center tap as well as the secondary I adjusted accordingly to the diagram as well as setting it for the desired output on secondary. though when I tested this setup it worked but once side of the transformer overheated and shut down, I have not tested it since then and I am not sure if I burned out the transformer; hopefully I didn't. If i didn't burn it out, is it possible to reverse feed the transformer by putting 240 on the secondary and using primary as output? Instead of being step down will it be a step up? Thank you in advance.
